Live Launch Coverage

>Tonight I am completely enthralled by NASA's Live Mission Coverage of the space shuttle Endeavour's preparation for launch.  I've already been watching for an hour and a half.  I've seen all the astronauts get suited up and strapped in.  They have just closed the access hatch with just over 2 hours until launch.  The NASA TV feed's only audio is the team's radio communication.  There are times when it's totally silent.  I guess you could argue that it is not that interesting... but I'm completely memorized.  Good thing I didn't have any plans tonight because I can't pull myself away!
